摘要: 建立了一套半导体激光器噪声测量系统用于生产测量和科学研究,其特点是简易,且兼容性大。用该系统对相关的半导体激光器(不同腔长,镀膜与不镀膜等)进行了测量研究,着重研究了镀膜与不镀膜的条件对激光器噪声特性的影响,发现镀膜后管芯一致性提高、受反馈影响增大。为实际生产提供了改进建议,即需要针对实际应用来精心选择端面镀膜的反射率,前端面镀膜反射率不能太低。

Abstract: The goal of this article is to present a measuring system,which is appropriate to industry measuring and science research,for relative intensity noise (RIN) of semiconductor lasers.The advantage of the system is simple and flexible.The RINs of some semiconductor lasers (with different cavity length,with or without coating)were measured.Special attention was paid to the effect of coating on the RIN.It is found that the quality stability of the lasers will be improved and the RIN character will be more sensible to feedback with coating than the lasers without coating.The reflectivity of coating should be chosen carefully according to the real application conditions,and the reflection of the front facet coating should not be too small.
